GATE.

SPECIFICATION forming part of Letters Patent No. 605,860, dated June 21,1898.

Application filed August 80, 1897. Serial No. 649,961. (No model.)

To all whom it may concern; I

Be it known that I, GRANVILLE DAVIS, a citizen of the United States,residing at North Salem, in the county of Hendricks and State ofIndiana, have invented certain new and useful Improvements in Gates; andI do declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to whichitjap pertains to make and use, the same, reference being had to theaccompanying d rawings, and to the letters of reference marked thereon,

. which form a part of this specification.

My invention relates to an improvement in gates, and of that class ofgates usually made in large sizes for the passage of vehicles; and itconsists of a gate and support easily portable embodying a certaincombination and arrangement of elements whereby the gate may be easilyoperated and retained either in a closed or opened position and wherebythe gate may be positively and conveniently manipulated from eithersidethat is, opened from one side and closed from the other or opened orclosed from either side.

The object of my invention is to prevent the sagging of the gate and toprovide a means whereby the gate may be opened or closed partially bygravity without much exertion on the part of the operator.

A further object of my invention is to construct a gate which may bereadily moved from place to place and effectually to prevent animalsfrom opening it.

Another object of my invention is to construct a gate capable of thefunctions above described in a simple and economic manner.

My invention consists in the novel construction and combination of theseveral parts, as will be hereinafter more fully set forth and pointedout in the claims.

Referring to the accompanying drawings, Figure 1 represents a sideelevation of the gate partially opened. Fig. 2 is an end elevation fromthe front; and Fig. 3, a plan view of the same, a portion of one of thearms bein g broken away.

The gateL may be made in any approved manner. "Usually it is formed fromaseries of slats a, longitudinally located and connected by a suitablebrace 'g and by the uprights 6. The top slats d extend rearwardly asuitable distance and are provided with a pulley Kpmounted upon theslotted bracket 11, the said extending slats being connected to the mainframe of the gate by means of the diagonal brace Z.

I mount at a suitable distance upon the sills R and R the upright postsA, B, and O oneach side of the gate. The lower ends of these posts aresuitably secured to the sills R and braced by the braces a, and the topsof the same are connected by meansof the trackrail M. Upon a stringer S,between the posts A, B, and O at the bottom, is the track, having theinclines r and r in opposite directions with the upturned ends 1;. Theapex of the inclines is at or about the center between the posts B andC. On the lower horizontal slats d of the gate, near its rear end, ismounted the pulley 0 in a suitable bracket t. This pulley travels oversaid inclines. It is to be understood that the top rail M is interposedbetween said upright posts and secured thereto, this forming apassage-way or guide for said gate. Upon the posts 0 and at right anglesto the gate L is secured the horizontal bar E. Diagonal arms F and F aresecured,

.to the sill R and to the ends of the horizontal bar E and are providedwith suitable pulleys G and G, over which the ropes H and H are carried.Said ropes H and H extend downward through the stationary swivel-pulleysJ, secured to the end of the track-rail M, and are secured in an eye inthe pivotally-mounted lever m between the top slats d. A latch T islocated between the top slats d and is pivoted at o. Said latchT andleverm are connected by means of a Wire is. i

The horizontal slats e have their outer ends 1) extending slightlybeyond the gate-frame and are designed to enter the recess f between theguide-blocks P of the locking-post D to assist in making the gatemorerigid when in a closed position. The post'D is provided with a loopI, pivotally secured by a bolt 00 and adapted to be secured in anydesired position by a set-screw y. The rollers K and O are mounted uponrolling-bearings in the brackets n and t, which serve to reduce thefriction.

In operation, to open the gate the operator IOO Isl-J this would destroyits portability.

grips the handle 71. and pulls the same downward and outward, whichreleases the latch T from the loop I and causes the gate to travel upthe incline 0' until it reaches the apex of the incline, and the gatetravels the balance of the way by gravity. In closing the gate the sameoperation is repealed from the opposite side, and when the latch engagesthe loop the hook thereon will hold the gate secure until the latch isagain raised. The upturned ends 2' of the track 0* r serve as stops forthe wheel 0 and prevent a sudden jar against the post D, and likewisestop its backward movement.

It will be seen that my improved gate can be readily moved from place toplace by reason of its being mounted upon the sills R and It. The postsA, II, and 0 could be set in the ground in the usual manner withoutinterfering with the operation of the gate; but

The diagonal arms F and I" are preferably in two pieces on either sideof the sill. R and the bar E, with their upper ends, to which thepulleys Gand Gare attached,drawn together, as seen in Fig. 1. Thisconstruction serves more thoroughly to brace the framework.

It is obvious'to a skilled mechanic that a gate constructed as shown anddescribed is simple in construction and effective in use.

Ilaving thus described inyinvention, what I claim, and desire to secureby Letters Patent of the United States, is

1. In a portable farm-gate of the class described, havinga doubleinclined single track with upturned ends, and suitable bracedsupporting-posts mounted on sills, the combination of the gate Ii,consisting of the slats a, the diagonal brace the uprights e, therearwardly-projecting top slats (Z, supported by the diagonal brace Z,and the bottom slats d, with the slotted brackets 11 and l, in which aremounted the rollers K and 0; the trackrail M, secured between the topsof the posts A, I), and C, to engage the roller K; the stringer S,secured upon the sills It and It, between the posts A, ll, and C, tosupport the track 7' r; the horizontal bar I secured at its center tothe tops of the posts 0, the double, diagonal arms I and F, secured tothe sill R, and to the horizontal bar IQ, the pulleys G and G, upon theupper ends of the arms F and F, the swivel-pulleys J, secured to theinner end of the track-rail M, the ropes II and II, passing over thepulleys G, G, and .I, and secured to the pivotal lever m; the lever m,pivotally mounted between the top slats (Z; the pivotally-mounted latchT, connected with the lever m, by the wire 7t, and theloeking-post I),having an adjustable loop I secured by a bolt 0:, and adjusted by theset-screw 7 and having guide-blocks I, to receive the projecting ends Z)of the'slats (r, as set forth.

2. The combination of a portable [arm-gate, having a rearwardtriangularextension, provided at its outer extremity with a bracket tocarrying a loose roller K, and a bracket l secured upon the lower railat its rear end, earrying a loose roller 0, with the straight uppertrack M, and the double inclined lower track 1, against which bear said.rollers It and O, substantially as set forth.

In testimony whereof I allix my signature in presence of two witnesses,

G ANYILLE DAVIS.
